• Includes dedicated hardware security modules for secure boot and code protection.
• Features multiple communication peripherals including USB OTG and Ethernet MAC support.

Applications

• Industrial automation control systems
• Human-machine interface (HMI) displays
• Medical equipment controllers

Procurement Notes

Verify the specific suffix AN corresponds to the LQFP-100 package configuration. Confirm RoHS compliance status through official Microchip documentation. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification. Cross-reference the datasheet revision date to verify current errata and silicon revisions before finalizing procurement orders.

Selection Notes

Select this model when 512 kB Flash and 256 kB SRAM meet application requirements. Choose the LQFP-100 package for surface-mount compatibility with standard PCB footprints. Consider alternative packages like BGA if board space constraints require smaller form factors. Verify peripheral availability matches system connectivity needs.

Part Context

This component belongs to the SAM S70 family of microcontrollers designed for applications requiring high performance and advanced security. The series integrates the Cortex-M7 processor with various memory options and peripheral sets. It targets markets demanding robust processing capabilities in compact embedded solutions.

Replacement Considerations

ATSAMS70N19A-CFN offers identical core specifications but utilizes a 100-VFBGA package instead of LQFP-100. ATSAMS70J19A-MNT provides similar memory configurations in a 64-QFN package with reduced I/O count. Verify pinout compatibility and thermal characteristics when substituting these variants.
